Application filed. June 18, 1917. Serial No. 175,535.

1 0 (ZZZ to]: 0m it may @011 com Be it known that I, Crmnnns H. 001)- were), a citizen of the United States, residing at @cean Springs, in the county of Jackson and State of Mississippi, have invented a certain new and useful Improvement in Devices for Regulating the Temperature in Closed Vehiclesvof which the following is zit-specification.

This invention relates to devices for regulating the temperature in closed vehicles, and has for its object to provide a means for easily and quickly draining said refrigerating apparatus. The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a view showing the apparatus applied to a car.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is a plan view of one of the openings in the roof of the car and the parts associated therewith.

Like numerals refer to like parts throughout the several figures.

In carrying out my invention I provide at each end of the car one or more tanks 1 and 2. These tanks are connected by pipes 3 and 4:, and a temperature varying liquid is circulated through the tanks and pipes.

In the construction shown, a portion of the tank projects upwardly through the roof of the car, each tank being provided with an opening through which liquid is inserted, the opening being normally closed by closing devices 5 which may be plugs or of any other form. The liquid may be drawn out of the apparatus when it is de sired to recharge the apparatus.

In the construction shown, there is a discharge pipe 6 which connects with some part of the apparatus, such for example, as the pipe 4:, said discharge pipe being arranged so that the liquid can be discharged at any point desired. As herein shown, the end 7 of the discharge pipe empties into a waste pipe 8 which is used to conduct away the moisture which settles on the pipes'3 and 4. These pipes 3 and 4 are provided with troughs 9 to collect this moisture, the moisture passing into the trough 10 and then into the waste pipe 8. The discharge pipe 6 is provided with a valve 11. This valve has a controlling device consisting of a rod 12 which projects up through the top of the car. By rotating this rod 12, the valve may be opened or closed. The rod is preferably provided with the handle 13 by means of which it is controlled.

It will be seen, for example, if the valve 11 should be left open, or partially open, and the vehicle started on its journey, the liquid would escape and the cargo in the car'would become ruined. I provide some means for absolutely insuring against this condition. In the construction shown, an obstructing part 14: is connected with the rod 12 and is arranged so that when the valve is open. or partially open, this obstructing part projects into the opening 15 into which the closing device 5 fits. It will thus be seenthat whenever the rod 12 is moved to open the valve 11 to drain the car, this obstructing device is automatically moved into a position where it projects into the opening 15. If, for example, it is attempted to close this opening before the valve is completely closed, the closing device engages the obstructing device. and hence the receptacle cannot be closed. This attracts the attention of the operator and compels him to close the valve before he can put the closing device in position. When he moves the rod 12 so that the valve 11 is closed, the obstructing device 14: passes out of the way of the closing device 5. It will thus be seen that by means of this device. the drainage system cannot be left open so that the liquid will drain out of the apsaid actuating device and normally entirely outside of the boundaries of said charging opening when said valve is closed, one end thereof arranged to project into one of said charging openings when the valve is open so as to prevent the closing device from being moved to its closing position and 'a hendiei oi controlling the actuating device for the valve and said obstructing device. o

2, A device for regulating the temperature in closed vehicles comprising a plurality of separated tan s connected with said vehicles and located topposite ends there of, pipes connecting said tanks, said tanks provided with charging openings, a single discharge pipe for discharging the ma.-

terial from all of said tanks and pipes, a

valve controlling said discharge pipe, a rod connected with said valve and pro ect ng through the topoi the vehicle at one side 0% one of said charging openings said rod adapted when moved to open and close said valve, an obstructing device connected with said IOd and projecting into thc charging opening of one oi said tanks when the valve is open so as to prevent the ClOSlllglleVlUB from being moved to its closed position, said; obstructing device being moved out of the way of theclosing device so as to be en- ,tirely at one side oi the said closing device when the closing device is in its closed position and a'handle always out of the way of the closing device and connected with said rod for simultaneously moving the valve and the obstructingidevice.

3. A device for regulating the temperature in closed vehicles comprising a tank containing temperature varying material 1 neath said cover when the valve is men and r to be withdrawn from beneath said cover when the valve is closed, whereby the cover can onlyvbe placed in position when the valve is closed.

in testimony whereof I atlix my signature in the )resence of two witnesses this 29th day of day, 1917.

CHARLES H. WOODWARD.
